', ANTISLIPPING DEVICE.

Specification of Letters Patent.

Patented Oct. 22, 1918.

Application filed October 16, 1916. Serial No. 125,806.

To all whom it may concern:

Be it known that I', HENRY H. Woon, of

Oyster Bay, in the county of Nassau, and in the State of New York, have invented a certain new and useful Improvement in Antislipping Devices, and do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates particularly to attachments for shoes adapted to prevent slipping, and especially for shoe heels.

The object of my invention is to provide a construction which is adapted to be applied particularly to shoe heels, which will effectively prevent slipping, especially in the case of rubber heels. I have discovered that slipping is usually caused by the imperfect holding of the edge of the heel against the ground or floor, especially when the heel is tilted at an angle thereto, and it is the object of my invention, therefore, to provide means which will prevent the slipping of the heel at the edge thereof.

While my invention is capable of embodiment in many different forms, for the purpose of illustration I have shown only certain forms thereof in the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of a heel made in accordance with my invention, showing a plug located in the lower stratum of the heel;

Fig. 2 is a similar view of a modified form of my invention showing a plug extending entirely through the heel;

Fig. 3 is a similar view of a further modified form of my invention showing a plug located in a somewhat different position;

Fig. 4 is a plan view of the form of my invention shown in Fig. 2; and

Fig. 5 is a plan view of a modified form of my invention showing one large plug.

In Fig. 1 of the drawings, I have shown a heel 1, having a plurality of inclined downwardly directed plugs 2, which in this form of my invention are located in the lower stratum of the heel, and ending at the edge of the heel in such a manner as to extend a short distance above, as well as a short distance inside of the said edge of the heel. As shown in Fig. 2, plugs 2 may be arranged so as to pass entirely through the heel. As shown particularly in Fig. 4, there may be a plurality of such plugs located around the edge of the heel. These plugs 2 may be made of any desired shape and of any desired material, but I prefer to make them of cork, leather, fiber, or some other antislipping material, as, for example, any composition containing comminuted carborundum, bound together with any suitable adhesive, as, for example, a resin. These plugs may be secured in the composition in any suitable manner, as, for example, by means of glue, or by making the holes in the heel smaller than the plug so as to grip the same. The modification of my invention shown in Fig. 3 is the same as the form of the invention shown in Fig. 1, except that there are provided plugs 3, which end at the edge of the heel, and which do not extend above the same, but only in side of the edge. In the modification of my invention shown in Fig. 5, the construction is the same as that already described, except that there is a plug 4; which is long and narrow.

In the use of my invention, when a person is walking with shoes equipped with the heels constructed as described hereinabove, the edge of the heel will not be subject to slipping, as in the case of heels formerly in use, as the heel, especially when tilted at an angle to the ground or floor, will hold, because of the contact with one of the plugs 2 3, or 4 therewith.

The plug or plugs will securely grip the ground or floor, because of the forward slant of the same, and because of the fact.

that any pressure upon the same will be .in a direction longitudinal with regard to the plug or plugs, and in such a way as to thus obviate to a marked degree any great yielding of the plug when subjected to such pressure. It will be noted also that the direction of the pressure upon the plug is usually in a forwardly inclined direction, which is the position of inclination of the plug or plugs. Furthermore, the pressure upon the plug or plugs can only have the effect f forcing the same inwardly into the body of the heel so as to clamp the plug or plugs in the heel more tightly, instead of tending to strip oif the anti-slipping means from the heel in which it is secured.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention.

I claim 1. A heel having an anti-slipping plug 10- cated at the rear edge thereof, and diagoto the bottom edge, and a cork plug filling 10 nally directed inwardly and upwardly from said hole. the edge of the heel. 4:- In a device of the class described, a rub- 2.
